shfmt: Simplify the code, removing redundant pieces of syntax (i.e. removing "$" from vars in expressions).
$ shfmt --simplify ${filename}
try on your machine
The shfmt
command is a shell script formatter that helps in formatting and beautifying shell scripts. The --simplify
option is used to simplify and optimize the script's syntax.
In the command shfmt --simplify ${filename}
, ${filename}
is a placeholder for the actual filename of the shell script you want to format.
By running this command, the shfmt
tool will read the contents of the file specified by ${filename}
, simplify and optimize the script's syntax according to the rules defined by the tool, and then output the formatted script.
